Most of my boarding has been done out west. I went to Cataloochee in NC for the first time last season for one day.
At first I bundled up like I do out west, but it was like 35-42 effing degrees outside at the top of the hill and I had to strip down.
All you need is a sweat-wicking base layer to handle your sweat and a shell to keep the snow off of you.
In all honestly, a polyester/rayon hoodie will do the trick for most of your trips out.
Unless its a particularly cold/windy day or the snow guns are spraying on you, a standard snowboarding jacket is overkill for the tundra that you will be ice skating down.
I've never ridden during spring conditions out west, but I imagine that NC conditions are pretty close
Read on another forum: "If someone held a gun to my head and said, "You have to move to Salida tomorrow", I'd probably do it. If they told me I had to go to Breckenridge instead, I think I'd just let them pull the trigger."
